Question

Hawa is working two summer jobs, making  $9 per hour babysitting and making  $13 per hour tutoring. In a given week, she can work no more than 12 total hours and must earn a minimum of  $120. If Hawa worked 2 hours babysitting, determine the minimum number of whole hours tutoring that she must work to meet her requirements. Answer:

Calculate Earnings from Babysitting: First, we need to calculate the amount Hawa earns from babysitting for 2 hours. She earns $9 per hour babysitting. So, for 2 hours, she will earn 2 hours * $9/hour = $18.Determine Additional Earnings Needed: Next, we need to determine how much more money Hawa needs to make to reach her minimum weekly earnings of $120. She has already earned $18 from babysitting. So, she needs $120 - $18 = $102 more.Calculate Hours for Tutoring: Now, we need to calculate the number of hours she needs to work tutoring to make the additional $102. She earns $13 per hour tutoring. To find the number of hours, we divide the total amount she needs by her hourly tutoring rate: $102 ÷ $13/hour = 7.84615385 hours.Round Up to Whole Hours: Since Hawa can only work whole hours, we need to round up the number of hours to the next whole number because she can't work a fraction of an hour and she needs to meet the minimum earnings requirement. Therefore, she must work at least 8 whole hours tutoring.
